lVith the aforesaid objects in View the main body of the press is built up from steel or like bars a, beams b and stanchions secured together in any suitable form. Where a closed press is required, the framework is covered in with metal or wood sheets a, leaving, however, openings at the front and back through which the material is fed to or taken out of the machine. When a sufiicient amount of material has been placed in the machine it is pressed into small compass by a movable platen d, the openings referred to being closed during pressing by doors 6 mounted on hinge pins 7", the doors being suitably held in closed position.

An important feature of my invention relates to means for driving the verticallymovable platen d. For this purpose the latter has an arm or stud g at each end passing through a slot h in the side of the press frame. To each of these arms is adjustably connected the end of a wire cable z' or its equivalent which passes round guide pulleys j and k, mounted on studs m and 1s then anchored to the outermost point of a drum preferably a scroll orx-fusee; drum 1. Two of these drums nare fixedon' the ends ofa shaft- 0" located, 7 along with the gear' for driving them at the" base of the-presaso thatas the" drumsor scrolls n are rotatedan increasingpressure is gradually brought to bear on the materialbeing 'compressedfbetween the movable platen gland. the fixed head p of the press, the greatest pressureoccurring inthe case of" scrolls when the cables reach: the smallest diameters of the latter:- The endl'of' eaclicable is'fastenedt'o the fusee at" its largest diameter, so that the, cable gradually Winds from the larger end to the smaller "end, increasing the" power; and d'ecreasingthe speed: The scroll orother drums n are driven spur pinionsq and Wheels. 1 giving suitable reductions-- from the driving shaft 8. The latter is providedwith fast" and loose pul leys z, and at one endand-a brake d'rum .4;

at the other. It also carries pinions w gearmg into wheels 00. on the second motionsliaft y, this lattercarrying the pinions q previously mentioned as part'of' the reduction gear: The-brake drumo co-acts'with-apivoted brake shoe 2'which is brought against the brake drum to stop the rotation of the driving gear when the driving belt is on the loose pulley u and as the platen d descends to its lower position. The platen d puts the shoe in action by means of a rod 3, having a bent end 4, and link connections with the shoe. The platen engages the end 4 as it descends and moves the lever or arm 5 about its pivot pin 6.

The driving strap is automatically shifted from the fast 27 to the loose pulley 11., also by the action of the platen, to stop the press when the desired density of compression has been reached. This is carried out by means of a rod 7 and a link or lever connection having a bent end 8 to engage the platen in its upward stroke operating in conjunction with a slidable strap fork rod 9. The rod 7 is connected to a short shaft 10 by arm 11, such shaft having fixed on it another arm or catch 12 the free end of which engages with a recess 13 in the strap fork rod 9 to hold the latter in position during the pressing operation and keep the strap fork 14 opposite the fast pulley t. In this position aspring'15, having one end secured to the rod 9 at 16 and the other coupled to a fixed stud 17, is stretched ready for retraction when the required pressure between the lows the spring to slide the strap fork platens has been reached. The spring is put inthe charged position by sliding the strap fork rod 9 in its brackets 18 by the agency of handle 20. At the required point of compression the platen 0Z lifts the rod 7 referred to, disengages the catch 12 and alrod and ship over the beltto the loose pul- .ley u. When the belt is on the loose pulley,

the catch 12, is in engagement with a notch in thetop of a boss 21 on the rod 9 and the latter can only be set in position for start- 1 ing the press by first lifting the pivoted catch by means of handle 22 so that the operator is always fully conscious thathe is Y having the free ends of the flexible connec times secured to their larger end portions, and means for revolving the fusee drums simultaneously, and thereby raising the platen "with a constantly increasing pressure? a i 2. In a press, a vertical press chamber having avertical slot in one side,. a press platen, means, for raising the press platen provided with a revoluble brake drum, a;

pivoted brake shoe for, bearing on the brake drum, and a tappet rod having an end por tion which projects through the said slot' below the platen, said rod being operatively connected witli' the pivoted brake shoe so that the brake is applied by the platen before the platencompletes its down-stroke.

3. In a press,v a vertical press chamber having a vertical slot in one side, a press platen, means forraising the platen pro vided with fast and' loose belt pulleys, a belt-shifting rod, .a spring for slidingthe said rodto movethe belt from the fast pulley to theloose pulley, a pivoted catch whichnormally engages with the said rod,

and a ftappeturod having an end portion 1 which projects through the said slotabove the ,platen, said tappet rod being operatively connected with the said catch so that the belt isshifted onto the loose pulley by the springbefore the platen completes its upstroke; v ii {1. In combination with a press-[as set forth in claim 3, a notched boss on the said belt-shifting rod which engages with the said pivoted catch when the beltis on the loose pulley and therebyprevents the b.elt-' shifting rod from being operated until the pivoted catch 'is. disengaged byhandv In testimony whereof I have hereunto set my hand in the presence of two witnesses.
